To all whom #may concern.'

1 Be it knownnthat I; Gnoncn 'HZELMAN a citizen ofthe United "States, `residing at Test Brooklyn, in'the county offLee, State 'of Illinois,'have invented anewand useful PlowGuid`e-V7heelHolder; andi do hereby declare the following to be a'full, clear, and

i exactl description lof the-invention,l suchl as lwill enable others skilled in the art to which it appertains to make and use the same.

` The invention relates to tractor guide wheel holders andl f particularly to @holders for guide wheels of'plows of Athc't'ractorl 'type and has for its principal. object 'to provide means comprising a rockable bolt suspended and -rockable -in av horiZontal'posit-ion in a bearing carried by thesteeringcolumn said bolts being provided with` lugsada'pted to` engage on each side of one of the spokes of the guide wheel spider.V f

A further object tofprovide spring means whereby aslight'longitudinal movement will" be' i allowed to the horizontally disposed bolt thereby taking up the strain on the guide wheel spiderandalsofallowing a slight giventoft move through the"furrow".i`r

With the` above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed, it being understood that changes in VVthe precise embodiment of the invention may Y Vbe madewithin the scope of what is claimed the spirit of the l without departing from invention.

In the drawings Figure 1 is a planview ofa conventional form of guide wheel for tractor engines, showing the wheel holding devicel applied thereto. j Fig. 2 is a side view of the guide wheel showing part thereof broken away to show the device in engagement with the spoke of i the wheel. l r i Fg- 3 S a perspective view of the sup- POltiIlg bracket.

` Fig. if 's a perspective view the rock` able and slidable bolt. i

Referring to the drawings, the numeral 1 designates a conventional form fof guide wheel, used on tractors. It is 'to be understood that the particular type of steering wheel and post may vary according tothe type or make of tractor. ,The guide wheel 1 is secured on the upper end of the shaft 2 vwhich shaft is rotatably'mounted in a cas- Y Specification of Letters Patent.

ing 3. `The shaft 2 leads'toany conventional Y form of vmechanism for .guiding andv con- Y trolling the plows. vDuring a plowing oper` lation it is necessary for the 'plowsfto' be 'held in position'by means of the guide wheel i 1, however there are long stretchesfof plow- *'ing'fin which it is not necessary to moves the guide wheel 1, Yunder these `conditionsfthe constantV holdingo'f'the wheelbythe operator` of the tractor precludesfhim from'hav- 'j ing complete control? and giving'V complete. 'i attention to 'the other mechanismV of` the `tractor,\. tov overcome this the guide" wheel `holder 4lA isjprovi'ded. Theguide' wheel 4 comprisesv 'a bracket lformed from al single securely held in position. The upwardly extending portion of the bracket '5 is provided with outwardly extending arms 12,;

said arms having thereon transversely disposed bearings 13, `inV which bearings a transversely disposed bolt 14 is rockablyl mounted. The bolt 14 is Vpreferably. .frictionally held within the bearings 13 sothat when said bolt is lrockedbyfmea'ns of the operator grasping thehandle 15 it will`rel main in the position to which it has'been moved. `Substantially centrally of thefbolt 14 are upstanding lugsl which are adaptfv ed to engage on each sideY of one of the spokes 1? of the spider of the guideiwheel.4 During va plowing operation' it hasfbeen 'e l 10o found 44to be advisable to allowa slight resiliency or vibratingmovement tothe wheels and also to take rup the suddenv shock. To Y y accomplish this coil springs 17 are yprovided.

which coil springs surround the' bolt 14: and

are disposed between the lugs'l an-d the inner faces of the bearings 13,` Thus it will be 'seen that asv the plows movethrough-the Y ground thearm 11L of, thespiderbeingin engagement with the lugs 16, one or,` the other of the coil springs 17fwill be slightly. compressed according to the vibratingrmove'v ment of the wheels.v

T ,OFFICE lio Vhen the Wheel locking Vdevice is out of use the bolt lll is rocked so that the lugs 16 will extend downwardly. However when it is desired to move the wheel to another' position it will only be necessaryV to rock the bolt so that the lugs. 16 will be below the spokes of the spider, then revolve the wheels until the plows are in their proper 'position after which the lugs are again moved upwardly and into engagement with one oftheA arms of the spider thereby-holding the wheel in its new position.

To prevent the complete rotation of the bolt '14 a lug'18 -is provided thereon, said lug being so positioned as to engage one of the arms ll2 and limit the movement of said bolt. Y

The invention having been set forth what l is claimed VasA new and-,usefulv is LA holder for tractor guide wheels kof tractors, said holder comprising a bracket YVwhich may be supported inrany suitable j manner adjacent one'side of the wheel, said bracket having-'rotatably mounted in bearings thereof a transversely disposed bolt1 lugs spaced-from each other andcarried by Y saidbolt and means whereby said lugs may beI maintained 'inw engagement with each side of a spokeof the guide wheel or out of engagement therewith.

v2. A holder for tractor guide Wheels of tractors, said holder comprising Va bracket secured to the casing of the wheel shaft, said bracket extending `upwardly and having bearings transversely disposed at its ends, a

by the hand for 'rocking the ried by the upper end' of the bracket,r a

frictionally. held rockable shaft mountedin said bearings, said shaft having substantially centrally disposed spaced lugs adapted to be moved .upwardly to engage and hold 'a'spole of the wheel orfdownwardly to release the spoke, means for limiting the rockable movement of the shaft, coil springs ,sur rounding the shaft and ,disposed between the lugs-and their adjacent bracket bearings, said springs forming means forV allowing the vibration of the wheel during a plowing operation and means adaptedY to be grasped shaft as dcsired.
